AI-Native CRMs Capturing Startup Market — Lightfield ($81M, 2,500 Cos in 3 Months), Monaco ($35M), Attio ($116M)

SaaStr·medium signal

SaaStr reports the vast majority of current YC startups are using neither Salesforce nor HubSpot. Lightfield (Tome founders' pivot, $81M raised, $300M valuation) hit 2,500 companies in three months and launched a one-hour CRM migration agent in March. Monaco, launched February 2026 by ex-Brex CRO Sam Blond with $35M from Founders Fund, and Attio ($116M total, GV-led Series B) round out the AI-native CRM tier. The pattern: these startups auto-populate pipelines from email, never require manual data entry, and treat the CRM as a memory layer for agents rather than a UI for humans.
